Electrolytes in a perm solution play a crucial role in the chemical process of perming hair. They facilitate the breaking down and rearranging of the hair's bonds, specifically the disulfide bonds that give hair its natural shape and texture. When the perm solution is applied, the electrolytes assist in penetrating the hair shaft and destabilizing these bonds. This allows the hair to be reshaped into the desired curls or waves once the solution is neutralized with a fixing agent.

Understanding this function is vital for professionals in the cosmetology field, as it highlights the chemical interactions at play during the perming process. It also emphasizes the importance of using the correct formulation to achieve optimal results while maintaining the health of the hair.
